Nvidia geforce 6800GT, jesus I love this baby. It is the most advanced graphic chipset at the moment. It cost me 400$ but hell you paid for what you get and in this case you hot a lot. No mather how much ram do you have, how fast your cpu is, without good graphic card you are in big whole and games will not run like they suppose to. I play all games with max resolution and card can handle it without any probs, more advanced Pixel shader 3 can handle very tough Antiztrofic filktering and antialiasing which generates quality image better then anything you can see. Nvidia is a great company and I love their driver support, which never failed me like with ati where bugs in fdrivers are well known. After I changee CPU adn mobo this beuty wil stay in my system bcause it's even now best card available. Here are specs from PNY website
